8" Radius Blocks

About This Item

Accurately true or change a fingerboard's radius and level frets.
We make these hardwood blocks for use with Stikit Abrasives, to radius a fretboard quickly, accurately and without guesswork.

Shaping fingerboards: use 80 through 220-grit
Leveling frets: use 220 through 400-grit

When working on compound radius fretboards, simply change blocks as you progress along the neck.

Dimensions: 8" (203.20mm) long x 2-3/4" (69.85mm) wide

See our shorter blocks for spot leveling, and for use as clamping cauls when gluing frets.

What's your radius?
Quickly find the curvature of a fingerboard or bridge with a set of radius gauges. Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape—a mistake that's easy to make and hard to fix.

Good idea, not very good quality

By

These blocks do the job, but mine are just not even, some has backbow, some has upbow, not very major, but for me it's just not acceptable. Check yours with a straight edge.

K.I.S.S!

These things are simplicity defined. After years of considering, evaluating and trying a multitude of radiusing methods, we finally decided to Keep It Simple Stupid! A nice low angle jack plane roughs out the radius and these handy blocks armed with gold stikit 80 grit gets the job done in under 10 or 15 minutes. 16 bucks for a piece of wood? Yeah. It's worth it. The accuracy is perfect and it makes what some people turn into a Rube Goldberg project into a fast, simple and accurate process. Thanks StewMac!

8" wooden radius sanding block

By
(Customer's Reviews)


well I'm not as strong in the forearms and shoulders as I was 20 years ago, but this block made short work of radiusing two oak fretboards for me recently (this is SOLID wood too). Works perfect with 1/2 sheet of paper and a little elbow grease. I couldn't be happier with the end result. excellent for cigar bax guitrs too. Great tool at a good price.

Great but a bit narrow for 5-string bass neck

By
(Customer's Reviews)


I used this block to level the Super Glue treatment of a fretless 5-string bass neck's fretboard. Had I checked the neck's top-end width before purchasing this block, I would have realized that it wouldn't be wide enough to sand the upper 1/3 of the neck's fretboard, so that's my error. Even so, this block worked great for the lower 2/3 of the 5-string bass neck. I followed Dan Erlewine's "Super Glue Savior" method and the block helped me to achieve a very acceptably smooth and glossy fretboard finish.

Excellent Tool

The radius sanding block works wonders for those round over jobs on fret boards. I purchased the 20" radii block and it did a great job. I was amazed how fast it shaped the fret board. It left a perfect radii and smooth finish. If you tried this w/o the block you would be in a world of hurt and probably have to buy several new fret boards.

I check each with a straightedge along the string line & they have been pretty much always dead-on. Price is reasonable too!

Good but need the option of a longer version

By
(Customer's Reviews)


These are great but could have been made longer. If twisting seems to be a concern a couple of reinforcement rods could be inserted. I just can't justify paying for the aluminum version that is 18" long. Being shorter doesn't seem to give you the warm and fuzzy feeling that the whole neck is uniformly covered. going over it again with my ground flat bottom bar that runs the whole length of the neck (added step) seems redundant. Overall good
